As I remember, the California Indian casinos also used drop chips for the blackjack games. There was a fifty cent or more "ante" to play a hand of BJ and the dealer color-changed the total of the "antes" each hand using $2.00 and $3.00 denom drop chips to leave the fifty cent and $1.00 chips in the rack.

Did the rules change for Indian casino BJ with the new legislation?
